How to disable (multi-level return) stack without catch / try / raise?

Question

I would like to spin the stack to an arbitrary level when catch / try not available (i.e. the code I'm deploying is out of control). Is it possible?

For example, during testing, I would like my tests to call a method that checks the preconditions, and unwind the caller if these preconditions are not met (resume in caller[1] ). Since the test harness failed, I cannot configure the catch in the appropriate place.

Answer 1

No. The only other mechanism for tiered returns is callcc , but it also requires creating a continuation at a level that is not controlled.

However, nothing came out of your control in Ruby: you could have a method alias in a test environment and add whatever code you would like.
